A method and apparatus for identifying a condition of assembly. The system includes a storage device having first and second disk partitions, a mode controller and a master boot program. Each coil is designed for imaging one leg, and when used together, both legs are imaged simultaneously. The application of a vacuum is preferably carried out by placing the container with liquid in a receptacle containing a liquid to be boiled, heating the liquid to boil the same and thereafter condensing the vapor with the receptacle sealed to develop a very high vacuum which draws the air out from the lower chamber of the container. Taking into account the subject’s menstrual cycle, the control unit identifies a baseline value of the clinical parameter, compares the identified clinical parameter to the baseline value, and, in response to the comparing, the control unit determines whether a clinical episode is predicted, determines whether a clinical episode is currently occurring, andor monitors an occurring clinical episode.
